还应理解，在本申请实施例中，终端可以包括但不限于应用于物联网中的终端设备，例如，可以是接入NB-IoT中的终端设备(可以称为“NB-IoT终端”)：智能抄表设备、物流追踪设备、环境监测设备等。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备也可以称为接入网设备或无线接入网设备，如网络设备可以是基站。本申请实施例中的网络设备可以是指将终端设备接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)。基站可以广义的覆盖如下中的各种名称，或与如下名称进行替换，比如：节点B(NodeB)、演进型基站(evolved NodeB，eNB)、下一代基站(next generation NodeB，gNB)、中继站、接入点、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、主站MeNB、辅站SeNB、多制式无线(MSR)节点、家庭基站、网络控制器、接入节点、无线节点、接入点(access piont，AP)、传输节点、收发节点、基带单元(base band unit，BBU)、射频拉远单元(Remote Radio Unit，RRU)、有源天线单元(active antenna unit，AAU)、射频头(remote radio head，RRH)、中心单元(central unit，CU)、分布式单元(distributed unit，DU)、定位节点等。基站可以是宏基站、微基站、中继节点、施主节点或类似物，或其组合。基站还可以指用于设置于前述设备或装置内的通信模块、调制解调器或芯片。基站还可以是移动交换中心以及设备到设备(device-to-device，D2D)、车辆外联(vehicle-to-everything，V2X)、机器到机器(machine-to-machine，M2M)通信中承担基站功能的设备、6G网络中的网络侧设备、未来的通信系统中承担基站功能的设备等。基站可以支持相同或不同接入技术的网络。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。

对于处于无线资源控制(radio resource control，RRC)空闲态的终端设备而言，终端设备可以通过初始接入的方式与基站建立RRC连接。初始接入的过程可以包括小区搜索、上行同步等。
小区搜索可以指终端设备实现与基站下行时频同步并获取服务小区标识(identity，ID)的过程。在小区搜索过程中，终端设备可以检测同步信号/物理广播信道(synchronization signal/physical broadcast channel，SSS/PBCH)(简称为SSB)。而对于上行同步，终端设备可以通过随机接入的方式获得与基站的上行同步。
随机接入的方式有两种，一种是基于竞争的随机接入，另一种是基于非竞争的随机接入。下面结合图2和图3对这两种随机接入方式进行描述。
图2是本申请实施例提供的一种基于竞争的随机接入方法的流程图，该方法包括步骤S210～步骤S240。
在步骤S210中、终端设备向网络设备发送随机接入过程中的消息1(message 1，MSG1)，该消息1中包括前导码(preamble)。
终端设备可以选择随机接入信道(random access channel，RACH)资源和前导码，并在选择的资源上发送选择的前导码。该RACH资源也可以称为物理随机接入信道(physical random access channel，PRACH)资源。
网络设备可以通过广播的形式向终端设备发送PRACH的配置信息。PRACH的配置信息可以包括PRACH的时频资源的配置信息以及起始的前导码根序列的配置信息。基于PRACH的配置信息可以确定与该网络设备对应的前导码或前导码集合。
网络设备可以为终端设备配置一个共享的前导码池。该前导码池中的前导码由多个终端设备共享。终端设备可以基于一定的策略选择前导码。由于前导码为多个终端设备共享，因此，会存在多个终端设备选择相同的前导码的冲突情况。为了解决该冲突，网络设备可以使用后续的解决机制来处理这种冲突。
在步骤S220中、网络设备向终端设备发送MSG2，该MSG2也可以称为随机接入响应(random access response，RAR)。该MSG2可以通过物理下行控制信道(physical downlink control channel，PDCCH)承载。
终端设备发送MSG1后，可以开启一个随机接入响应时间窗，并在该时间窗内监测随机接入无线网络临时标识(random access-radio network temporary identifier，RA-RNTI)加扰的PDCCH。RA-RNTI与终端设备发送MSG1所使用的RACH的时频资源有关。终端设备接收到PDCCH后，可以使用RA-RNTI对该PDCCH进行解码。
MSG2中还可以包括终端设备发送的前导码，如果终端设备接收到用RA-RNTI加扰的PDCCH，并且MSG2中包含自己发送的前导码，则终端设备可以认为成功接收到随机接入响应。
终端设备成功接收到PDCCH后，终端设备能够获得该PDCCH调度的物理下行共享信道(physical downlink shared channel，PDSCH)，其中，该PDSCH中包含了RAR。该RAR可以包含多个信息。例如，RAR的子头(subheader)中可以包含回退指示(backoff indicator，BI)，该BI可用于指示重传MSG1的回退时间；RAR中的随机接入前导码标识符(random access preamble identification，RAPID)指示网络设备响应收到的前导码索引；RAR中的负载(payload)中可以包含定时提前组(timing advance group，TAG)，该TAG可用于调整上行定时；RAR中还可以包括上行授权(UL grant)，用于调度MSG3的上行资源指示；RAR中还可以包括临时小区无线网络临时标识(cell-radio network temporary identifier，C-RNTI)，对于初始接入的终端设备来说，终端设备可以使用该临时C-RNTI解码MSG4的PDCCH。
如果终端设备在随机接入响应时间窗内未接收到RAR，或者未能验证成功，则表示响应失败。在该情况下，如果终端设备随机接入的尝试次数小于上限值(如10次)，则终端设备可以继续尝试进行随机接入。如果尝试次数大于上限值，则表示随机接入失败。
步骤S230、终端设备向网络设备发送MSG3。终端设备可以在网络设备调度的上行授权上发送MSG3。该MSG3也可以称为RRC连接建立请求消息。
该MSG3主要用于通知网络设备该随机接入过程是由什么事件触发的。MSG3中包括终端设备的C-RNTI。在不同的场景中，终端设备发送的MSG3会有所不同。下面对一些场景进行举例说明。
例如，对于RRC连接建立场景，终端设备可以通过MSG3发送RRC连接建立请求消息，该RRC连接建立请求消息可以携带非接入层(non-access stratum，NAS)UE_ID。该RRC连接建立请求消息可以通过无线链路控制(radio link control，RLC)层传输(transmitting，TM)中的公共控制信道(common control channel，CCCH)传输。该消息没有分段。
又例如，对于RRC连接重建请求，终端设备可以通过MSG3发送RRC重建请求消息，该RRC重建请求消息不携带NAS消息，该RRC重建请求消息可以通过RLC层的CCCH用TM传输。该消息没有分段。
再例如，对于小区切换场景，如果终端设备接入目标小区，并且在切换过程中没有专用的前导码，则可以触发基于竞争的随机接入。终端设备可以通过MSG3发送RRC切换确认消息和C-RNTI。RRC切换确认消息和C-RNTI可以通过专用控制信道(dedicated control channel，DCCH)传输。在一些实施例中，MSG3还可以携带缓冲区状态报告(buffer status report，BSR)。
步骤S240、网络设备向终端设备发送MSG4。
该MSG4具有两个作用，一个是用于竞争冲突解决，另一个是向终端设备发送RRC配置消息。如果终端设备在MSG3中携带了C-RNTI，如RRC重建过程，则MSG4采用该C-RNTI加扰的PDCCH调度，相应地，终端设备可以使用MSG3中的C-RNTI对PDCCH进行解码，得到MSG4。如果终端设备在MSG3中没有携带C-RNTI，如初始接入，则MSG4可以采用临时C-RNTI加扰的PDCCH调度，相应地，终端设备可以使用MSG2中的临时C-RNTI对PDCCH进行解码，得到MSG4。终端设备在解码PDCCH成功后，得到承载MSG4的PDSCH。终端设备可以将该PDSCH中的公共控制信道(common control channel，CCCH)服务数据单元(service data unit，SDU)与MSG3中的CCCH SDU进行比较，如果两者相同，则表示竞争解决成功。竞争解决后，临时C-RNTI转正 为C-RNTI(The Temporary C-RNTI is promoted to C-RNTI for a UE which detects RA success and does not already have a C-RNTI；it is dropped by others)。
对于切换、上/下行失步状态下的数据传输等随机接入场景，此时因为终端设备已经分配了C-RNTI，在MSG3中的MAC CE中，终端设备可以向网络设备通知C-RNTI，因此，基站可以使用C-RNTI加扰的PDCCH调度MSG4，而不使用临时C-RNTI调度的MSG4(The C-RNTI on PDCCH for UE in RRC_CONNECTED)。终端设备解码出PDCCH调度命令的时候表示完成竞争解决，MSG4中的具体内容已经与竞争解决无关。这时，MSG2中由基站分配的TC-RNTI失效，后续由基站继续分配给其它UE使用(A UE which detects RA success and already has a C-RNTI,resumes using its C-RNTI)。因此，此种场景MSG4中不包括UE竞争解决标识。
图3是本申请实施例提供的一种基于非竞争的随机接入方法的流程图。该方法包括步骤S310～S330。
在步骤S310中，网络设备向终端设备发送前导码配置信息，该配置信息中包括随机接入过程中需要的前导码和PRACH资源。该前导码为网络设备为终端设备分配的专用前导码。专用前导码可以通过RRC信令或物理层(physical，PHY)信令(如PDCCH中的DCI)通知给终端设备。使用专用前导码不会存在与其他终端设备发生冲突的问题。
在步骤S320中，终端设备可以根据该前导码配置信息，向网络设备发送MSGA，也就是说，终端设备可以在该RACH资源上向网络设备发送该前导码。
在步骤S330中，网络设备向终端设备发送MSGB，该MSGB中可以包括RAR。终端设备接收到该RAR后，表示该随机接入过程结束。
在一些应用场景下，需要对终端设备进行定位。例如，物流监控、车辆管理、公共安全、天气预报、辅助导航等。
根据定位精度的不同，定位方式可以包括粗定位和精定位。本申请实施例主要介绍粗定位方式。常见的粗定位方式可以包括基于cell-id进行定位的方式，基于cell-id定位的技术也可以称为CID定位。其实现原理可以为：定位平台向核心网发送信令，以查询终端设备所在小区的ID。然后定位平台可以根据存储的基站数据库(base station almanac，BSA)中的数据，确定终端设备的大致位置。这种定位方式的定位精度取决于基站或小区的大小，一般在几百至几千米左右。相对高精度定位而言，粗定位业务复杂度较低。
另外，基于cell-id的定位技术需要终端设备支持定位操作。在进行定位的过程中，终端设备需要进入定位操作流程，且该定位操作流程需要终端设备进入RRC连接态。终端设备可以接收定位服务请求，并针对定位能力进行上报。终端设备可以基于定位服务器的指示进行定位测量，并将测量结果发送给定位服务器，由定位服务器进行位置估计。该定位过程较为复杂，延迟较高。
基于cell-id的定位技术存在定位精度不高的问题。为了提高定位精度，出现了增强CID(enhanced CID，E-CID)的定位技术。E-CID可以指在cell-id的基础上，增加了一些其他的信息(如到达角(angle-of-arrival，AOA)、定时提前量(timing advance，TA)等)进行辅助定位，从而提高定位精度。E-CID定位技术可以包括：cell-id+AOA，cell-id+TA，cell-id+AOA+TA等。下文主要介绍基于AOA的定位方式。
在一些无线通信系统(如NR、LTE等)中，可以支持基于AOA的定位。AOA可以表示基站相对终端设备的方向信息。该定位方式是指可以利用终端设备的信号发送至基站的入射角度，来确定终端设备的位置。基站获取AOA信息，需要终端设备具有定位的功能，并且启动定位相关操作和信令。另外，终端设备需要进入RRC连接态，并且按照与CID定位类似的过程进行定位，这些增加了定位的复杂度和时延。
由上可知，终端设备为了获取AOA信息，需要进入RRC连接态。只有处于RRC连接态或RRC非激活态的终端设备，才能够获得定位导频的相关配置信息(如探测参考信号(sounding reference signal，SRS))，从而才可以对终端设备进行定位。
由上可知，为了提高定位精度，可以进一步确定基站相对终端设备的方向信息(如AOA)。但是，目前确定上述方向信息的方式存在时延较大，流程复杂的问题，不利于降低终端设备的定位时延。
基于此，本申请实施例提供一种用于定位的方法，终端设备可以在初始接入的过程中获取与终端设备相对基站的方向信息相关联的第一信息，也就是说，终端设备可以在进入RRC连接态
(connected)或RRC非激活态(inactive)之前获取该第一信息，从而能够降低终端设备获取方向信息的时延，有利于降低定位时延。
下面结合图4和图5，对本申请实施例的方案进行详细介绍。
参见图4，在步骤S410、终端设备在初始接入过程中获取第一信息，该第一信息用于对终端设备进行定位，该第一信息与终端设备相对基站的方向信息相关联。
参见图5，在步骤S510、基站向终端设备发送初始接入过程中的第二信息。该第二信息用于确定第一信息，该第一信息用于对终端设备进行定位。第一信息与终端设备相对基站的方向信息相关联。第一信息是基于第二信息确定的。在一些实施例中，第二信息与第一信息相同。在另一些实施例中，第二信息与第一信息可以不同。
下文介绍的方式对图4和图5同样适用。
本申请实施例中的基站可以指终端设备在初始接入过程中选择的小区对应的基站。本申请实施例中的终端设备可以为处于RRC空闲态(idle)下的终端设备，或者，该终端设备可以为进行初始接入的终端设备。
本申请实施例对第一信息的内容不做具体限定。作为一个示例，第一信息可以包括终端设备相对基站的方向信息。作为另一个示例，第一信息也可以包括基站相对终端设备的方向信息。
在一些实施例中，终端设备相对基站的方向信息与基站相对终端设备的方向信息是相对应的，只要知道了其中一个方向信息，就可以推算出另一个方向信息。例如，如果已知终端设备相对基站的方向信息，也就可以确定出基站相对终端设备的方向信息。又例如，如果已知基站相对终端设备的方向信息，也同样可以确定出终端设备相对基站的方向信息。在一些实施例中，当系统为频分双工(frequency duplex division，FDD)系统，可以认为系统具有上下行互易性，对于上下行方向信息中，只要知道了其中一个方向信息，就可以推算出另一个方向信息。
终端设备相对基站的方向信息可以通过基站向终端设备发送信号，终端设备确定该信号的方向信息来得到。基站相对终端设备的方向信息可以通过终端设备向基站发送信号，基站确定该信号的方向信息来得到。
在一些实施例中，基站相对终端设备的方向信息例如可以为AOA信息。终端设备可以向基站发送信号，基站可以对该信号进行测量，从而得到AOA信息。在一些实施例中，第二信息可以包括AOA信息。基站可以向终端设备发送AOA信息。也就是说，基站可以在基于终端设备发送的信号测量得到AOA信息后，可以向终端设备发送AOA信息。
在一些实施例中，终端设备可以向基站发送第一指示信息，该第一指示信息用于指示基站进行AOA测量，或，第一指示信息用于指示基站进行AOA反馈。下文以第一指示信息用于指示基站进行AOA测量为例，对本申请实施例的方案进行描述。
该第一指示信息可以承载于随机接入过程中的消息中。通过随机接入过程，终端设备向基站指示进行AOA测量，有利于终端设备在随机接入的过程中获得AOA信息，从而降低定位时延。
本申请实施例对基站进行AOA测量的方式不做具体限定。例如，基站可以基于承载第一指示信息的信号，进行AOA测量。又例如，基站也可以基于其他信号(如没有承载第一指示信息的信号)，进行AOA测量。
本申请实施例中的随机接入方式可以为基于竞争的随机接入方式(也称为四步随机接入)，也可以为基于非竞争的随机接入方式(也称为两步随机接入)。
本申请实施例对第一指示信息的指示方式不做具体限定。作为一个示例，以基于竞争的随机接入为例，可以通过随机接入过程中的MSG1承载第一指示信息，或者，也可以通过随机接入过程中的MSG3承载第一指示信息。作为另一个示例，以基于非竞争的随机接入为例，可以通过随机接入过程中的MSGA承载第一指示信息。
在一些实施例中，本申请实施例中的第一指示信息可以与前导码关联。也就是说，第一指示信息可以通过与前导码相关联的信息进行指示。该前导码可以为MSG1中的前导码，也可以为MSGA中的前导码。通过复用前导码来指示第一指示信息，可以节省信令开销，有利于降低定位的复杂度。
在一些实施例中，第一指示信息可以与以下信息中的一种或多种关联：前导码的索引、前导码的加扰信息、前导码序列。在一些实施例中，前导码的索引也可以称为前导码的序号。
在一些实施例中，第一指示信息可以与前导码的索引相关联，也就是说，终端设备可以通过前导码的索引来指示第一指示信息。例如，可以通过特定的前导码索引来指示第一指示信息。如果终端设备需要基站进行AOA测量，则终端设备可以向基站发送索引为该特定索引的前导码。
基站接收到终端设备发送的前导码后，可以根据前导码的索引，确定是否进行AOA测量。如果该前导码的索引为特定索引，则基站进行AOA测量；如果前导码的索引不是特定索引，则基站可以不进行AOA测量。
下面以第一索引需要进行AOA测量，第二索引不需要进行AOA测量为例，对本申请实施例的方案进行介绍。
本申请实施例对第一索引的取值不做具体限定。例如，第一索引的取值可以为偶数。又例如，第一索引的取值可以为奇数。再例如，第一索引的取值可以为某一范围内的值。如，第一索引的取值可以大于或等于第一值，和/或，第一索引的取值可以小于或等于第二值。
本申请实施例对前导码索引的编号方式不做具体限定。作为一个示例，可以将前导码集合中的前导码按顺序进行编号，不同前导码的索引不同。作为另一个示例，可以将前导码集合中的前导码分成多个组，每个组中的前导码独立编号。例如，可以根据SSB与前导码的对应关系对前导码进行分组，一个SSB对应的前导码为一个前导码组，每个前导码组中的前导码可以独立进行编号。
举例说明，在初始接入过程中，终端设备可以读取高层参数获得SSB与RO之间的映射关系，从而得到两个参数N和R。其中，N表示一个随机接入机会(RACH occasion，RO)关联的SSB个数，R表示一个SSB对应的前导码的个数。如果N≥1，对于第n个SSB，其前导码的索引从n*Ntotal/N开始，其中，Ntotal表示用于随机接入的前导码的总数。在本申请实施例中，可以对一个SSB对应的R个前导码进行编号，假设第一个前导码的序号为0，后续的前导码可以依次进行编号。
在一些实施例中，第一指示信息可以与前导码的加扰信息相关联，也就是说，终端设备可以通过前导码的加扰信息指示第一指示信息。作为一个示例，终端设备可以通过是否对前导码进行加扰来指示第一指示信息。如果终端设备需要基站进行AOA测量，则终端设备可以对前导码进行加扰，即终端设备向基站发送加扰后的前导码；如果终端设备不需要服务小区进行AOA测量，则终端设备可以不对前导码进行加扰，即终端设备向基站发送未加扰的前导码。
基站接收到前导码后，可以根据前导码是否加扰，确定是否进行AOA测量。如果接收到的前导码进行了加扰，则基站可以确定需要进行AOA测量。如果接收到的前导码未加扰，则基站可以确定不需要进行AOA测量。
作为又一示例，终端设备可以通过特定的加扰信息来指示第一指示信息。如果终端设备需要基站进行AOA测量，则终端设备可以使用特定的扰码对前导码进行加扰。如果终端设备不需要基站进行AOA测量，则终端设备可以使用其他扰码对前导码进行加扰。
基站接收到前导码后，可以根据前导码的扰码信息，确定是否进行AOA测量。如果接收到的前导码采用的是特定的扰码进行的加扰，则基站确定需要进行AOA测量。如果接收到的前导码采用的不是特定的扰码进行的加扰，则基站确定不需要进行AOA测量。
下面以第一扰码需要进行AOA测量，第二扰码不需要进行AOA测量为例，对本申请实施例的方案进行介绍。
在一些实施例中，第一扰码可以为Walsh码，第二扰码可以为全1序列。如果前导码的扰码为Walsh码，则服务小区的基站需要进行AOA测量。如果第一扰码为全1序列，则服务小区的基站不需要进行AOA测量。在另一些实施例中，第一扰码可以为全1序列，第二扰码可以为Walsh码。如果前导码的扰码为全1序列，则服务小区的基站需要进行AOA测量。如果前导码的扰码为Walsh码，则服务小区的基站不需要进行AOA测量。
在一些实施例中，第一指示信息可以与前导码序列相关联，也就是说，终端设备可以通过前导码序列来指示第一指示信息。例如，终端设备可以通过特定的前导码序列来指示第一指示信息。如果终端设备需要基站进行AOA测量，则终端设备可以向基站发送特定的前导码序列。
该特定的前导码序列可以是新引入的前导码序列或专用前导码序列。例如，可以在原来的前导码集合中新增加一些前导码序列，这些前导码序列可用于指示基站进行AOA测量。如果需要基站进行AOA测量，终端设备可以向基站发送专用前导码序列；如果不需要服务小区的基站进行AOA测量，则终端设备可以向基站发送其他前导码序列。
基站接收到前导码后，可以根据前导码是否为专用前导码序列，确定是否进行AOA测量。如果接收到的前导码为专用前导码序列，则基站确定需要进行AOA测量。如果接收到的前导码采用的不是专用前导码序列，则基站确定不需要进行AOA测量。
在一些实施例中，上述专用前导码序列可以为Zadoff-Chu序列。
在一些实施例中，基站也可以通过随机接入过程中的消息向终端设备发送AOA信息，使得终端设备可以通过随机接入获得AOA信息。例如，基站可以向终端设备发送AOA信息，该AOA信息承载于随机接入响应消息中。通过随机接入响应消息承载AOA信息，可以使得终端设备能够尽快获得AOA信息，有利于降低定位时延。
在一些实施例中，如前文所述，第一信息可以包括终端设备相对基站的方向信息。本申请实施例对第一信息的确定方式不做具体限定。例如，第一信息可以基于SSB索引(index)与SSB波束发送方向之间的对应关系确定。在一些实施例中，第二信息可以包括SSB索引与SSB波束发送方向之间的对应关系，也就是说，基站可以向终端设备发送SSB索引与SSB波束发送方向之间的对应关系。
在一些实施例中，终端设备在进行随机接入之前，会进行SSB的检测，并检测出SSB的索引信息。SSB的索引不同，SSB的发送方向也会不同。终端设备在检测出SSB的索引信息后，可以根据检测出的SSB索引信息，以及SSB索引与SSB波束发送方向之间的对应关系，确定出SSB波束的方向。进一步地，终端设备可以基于SSB波束的方向，确定终端设备相对基站的方向信息。
在一些实施例中，SSB索引与SSB波束发送方向之间的对应关系可以由基站发送至终端设备。例如，基站可以通过广播消息向终端设备发送SSB索引与SSB波束发送方向之间的对应关系，即SSB索引与SSB波束发送方向之间的对应关系承载于广播消息中。
在一些实施例中，终端设备可以接收基站发送的SSB，并根据SSB的索引信息以及SSB的索引与SSB波束方向的对应关系，确定终端设备相对基站的角度。进一步地，终端设备可以基于该角度，确定终端设备的位置信息。例如，终端设备可以基于该角度以及基站的位置信息，确定终端设备的位置信息。
上文描述的基站可以为一个基站，也可以为多个基站。例如，上述基站可以为服务小区的基站，也可以为邻小区的基站。又例如，上述基站可以包括服务小区的基站和邻小区的基站。
如果基站包括服务小区的基站和邻小区的基站，则第一信息可以基于第一对应关系以及第二对应关系确定。第一对应关系可以包括服务小区的SSB索引和SSB波束方向之间的对应关系，第二对应关系可以包括邻小区的SSB索引与SSB波束方向之间的对应关系。第一对应关系可以由服务小区的基站发送，第二对应关系可以由邻小区的基站发送。
当终端设备进行下行同步信号搜索时，会搜索到多个小区的SSB信息，也就是说，终端设备搜索到的SSB信息中不仅包括服务小区的SSB信息，也包括邻小区的SSB信息。在一些实施例中，终端设备可以根据服务小区的SSB索引和SSB波束方向的对应关系，以及邻小区的SSB索引和SSB波束方向的对应关系，分别确定终端设备相对服务小区和相邻小区的方向。
在一些实施例中，终端设备可以对多个小区的SSB信息进行检测。以服务小区和邻小区为例，终端设备可以接收服务小区的基站发送的第一SSB，并基于第一SSB的索引以及第一对应关系，确定终端设备相对于服务小区的基站的第一角度。终端设备可以接收邻小区的基站发送的第二SSB，并基于第二SSB的索引以及第二对应关系，确定终端设备相对于邻小区的基站的第二角度。终端设备可以基于第一角度、第二角度、服务小区的基站的位置信息、邻小区的基站的位置信息，确定终端设备的位置信息。
上文介绍了由终端设备确定位置信息的方案，当然，终端设备的位置信息也可以由基站或定位设备来确定。终端设备可以将检测到的SSB信息发送至基站或定位设备，然后由基站或定位设备基于该SSB信息，确定终端设备的位置。
基站或定位设备确定终端设备位置的方式与终端设备自己确定位置的方式类似，未详细描述的部分可以参见前文的描述。
作为一个示例，终端设备可以将检测到的SSB索引信息发送至基站，基站可以基于SSB索引以及SSB的索引与SSB波束方向的对应关系，确定终端设备相对基站的角度。进一步地，基站可以基于该角度，确定终端设备的位置信息。例如，基站可以基于该角度以及基站的位置信息，确定终端设备的位置信息。
上述SSB索引可以包括第一SSB的索引和第二SSB的索引。基站(如服务小区的基站)可以基于第一SSB的索引以及第一对应关系，确定第一角度；基站可以基于第二SSB的索引以及第二对应关系，确定第二角度。基站可以基于第一角度、第二角度、服务小区的基站的位置信息以及邻小区的基站的位置信息，确定终端设备的位置信息。
举例说明，基站可以接收终端设备发送的第一SSB的索引，并基于第一SSB的索引以及第一对应关系，确定终端设备相对于服务小区的基站的第一角度。基站可以接收终端设备发送的第二SSB的索引，并基于第二SSB的索引以及第二对应关系，确定终端设备相对于邻小区的基站的第二角度。基站可以基于所述第一角度、所述第二角度、所述服务小区的基站的位置信息以及所述邻小区的基站的位置信息，确定所述终端设备的位置信息。
作为另一个示例，终端设备可以将检测到的SSB索引信息发送至定位设备，定位设备可以基于SSB索引以及SSB的索引与SSB波束方向的对应关系，确定终端设备相对基站的角度。进一步地，定位设备可以基于该角度，确定终端设备的位置信息。例如，定位设备可以基于该角度以及基站的位置信息，确定终端设备的位置信息。
上述SSB索引可以包括第一SSB的索引和第二SSB的索引。定位设备可以基于第一SSB的索引以及第一对应关系，确定第一角度；定位设备可以基于第二SSB的索引以及第二对应关系，确定第二角度。定位设备可以基于第一角度、第二角度、服务小区的基站的位置信息以及邻小区的基站的位置 信息，确定终端设备的位置信息。
举例说明，定位设备可以接收终端设备发送的第一SSB的索引，并基于第一SSB的索引以及第一对应关系，确定终端设备相对于服务小区的基站的第一角度。定位设备可以接收终端设备发送的第二SSB的索引，并基于第二SSB的索引以及第二对应关系，确定终端设备相对于邻小区的基站的第二角度。定位设备可以基于所述第一角度、所述第二角度、所述服务小区的基站的位置信息以及所述邻小区的基站的位置信息，确定所述终端设备的位置信息。
下面对基于第一角度、第二角度、服务小区的基站的位置信息、邻小区的基站的位置信息，确定终端设备的位置信息的方案进行举例说明。
假设第一角度为θ1，第二角度为θ2，服务小区的基站的位置为(xb1，yb1)，邻小区的基站的位置为(xb1，yb1)，终端设备的位置为(x，y)，终端设备的位置可以表示为：
上述x轴和y轴垂直。θ1和θ2可以为在xy坐标系下的角度。例如，y轴为正北方向，x轴为正东方向，θ1和θ2可以为相对正北方向的角度。
上述邻小区可以包括多个小区。例如，邻小区包括第一邻小区和第二邻小区，终端设备的位置可以基于终端设备相对多个邻区小区的角度来确定。通过联合多个小区对终端设备进行定位，可以提高终端设备的定位精度。
终端设备的位置坐标可以表示为：
其中，x轴和y轴垂直，(xb1，yb1)为服务小区的基站的位置坐标，(xb2，yb2)为第一邻小区的基站的位置坐标，(xb3，yb3)为第二邻小区的基站的位置坐标，θ1为第一角度，θ2为所述终端设备相对于所述第一邻小区的角度，θ3为所述终端设备相对于所述第二邻小区的角度，α表示权重系数。
上述α值可以基于终端设备针对邻小区的信号测量结果确定。例如，α值可以基于终端设备针对第一邻小区的信号测量结果和终端设备针对第二邻小区的信号测量结果确定。
下面以信号测量结果为参考信号接收功率(reference signal receiving power，RSRP)为例，α值可以基于以下公式确定：
RSRP1表示终端设备对第一邻小区的基站进行测量的RSRP值，RSRP2表示终端设备对第二邻小区的基站进行测量的RSRP值。
当然，可以理解的是，上述公式中的RSRP也可以换成信号测量结果中的其他值，如参考信号接收质量(reference signal receiving quality，RSRQ)。
需要说明的是，上文是以终端设备相对基站的角度为例，对终端设备的位置坐标的计算公式进行的举例说明，可以理解的是，上述公式对基站相对终端设备的角度也同样适用。由于终端设备相对基站的角度与基站相对终端设备的角度之间是互易的，因此，也可以基于基站相对终端设备的角度确定终端设备的位置坐标。
例如，可以基于服务小区的基站相对终端设备的角度、邻小区的基站相对终端设备的角度、服务小区的基站的位置信息以及邻小区的基站的位置信息，确定终端设备的位置信息。具体的确定方式可以参见前文的描述，为了简洁，此处不再赘述。上述邻小区可以包括多个小区，如邻小区可以包括第一邻小区和第二邻小区。上述基站相对终端设备的位置信息可以由基站测量得到。
本申请实施例的方案可以与其他定位方式结合使用。例如，本申请实施例确定的方向信息可以与cell id相结合，共同对终端设备进行定位。又例如，本申请实施例确定的方向信息可以与TA相结合，共同对终端设备进行定位。再例如，本申请实施例确定的方向信息可以与cell id以及TA相结合，共同对终端设备进行定位。
在一些实施例中，本申请实施例的定位方式可以与其他精定位方式相结合，实现对终端设备的精定位。由于本申请实施例可以降低获取方向信息的时延，因此，在该定位基础上进行精定位，能够降 低获取精定位信息的复杂度。
